I've got this unknown motor I was refurbishing because it sounded horrible, took it apart, cleaned it, replaced the bearings etc etc but when I put it back together and powered it up, I heard an arc and it began smoking. When I cracked it open the wire that leads from the centrifugal switch to the power center was completely burnt. Is there something I'm missing here? Did I miswire the leads backwards? The other wire leads to the starting capacitor.
